Today on TV market "running the show" LCD technology. And the most advanced kind of LCD TVs on the market of television technology is LED-TVs, LCD TVs is LED backlit. The main advantage of LEDs (LED Light Emission Diodes - light-emitting diode) is their efficiency - modern LEDs are very bright and emit 120 lumens to watts absorbed in power and compactness, which can significantly reduce the thickness of the TV cabinet. In this article we will focus on the key features and technologies t5 t8 implemented in LED-TVs that have a significant impact on their properties.
As we have said, the main feature LED-TV is to use LED lights, with LED-based illumination can be different. Today there are two main types - matrix (Direct LED) and boundary (Edge LED).
In the first case, the LEDs form a rectangular grid behind the LCD matrix, and the brightness t5 t8 can be adjusted in different parts of the screen independently, which allows for extremely high static contrast values, that bright areas of the image appear as bright, while the dark - as dark. On the other hand, such illumination requires t5 t8 a large number of LEDs and sophisticated t5 t8 control systems. Therefore matrix backlight is used only in high-end t5 t8 models of LED-TVs. An example of a matrix backlit TVs can serve LG 42LA620V and Sony KDL-32R423A. t5 t8
Regional lights easier and cheaper to implement, so it can not freely control the glow of different parts of the screen, but due to its simplicity is much cheaper, thanks to her our shops you can see a very inexpensive model LED-TVs. Such as Samsung UE22F5400AK or Panasonic TX-LR32EM6.
Finally, in recent years a proliferation of TVs with improved matrix backlit - RGB LED. Lightning does not consist of white LEDs, and triads of red, green and blue LEDs. So electronics TV is able to not only adjust the brightness of the screen, but also manage its color, which significantly extends the range of the image: TV can display more colors t5 t8 and more accurate t5 t8 transfer color transitions. Naturally, this illumination is expensive, so it is - the fate of most "cool" patterns of individual producers. Today, this popular highlighting advances, primarily, Sharp in their flagship sample Sharp LC-70LE835.
An important feature of the TV, which directly affects t5 t8 our perception of the image is the screen resolution. The higher t5 t8 the resolution, the smaller are the pixels that make up the image, and the more smooth and pleasing to the eye it will be. Is now the de facto standard resolution of 1920x1080 (Full HD). Today, virtually all television sets ranging from 32 inches with resolution of Full HD.
On the other hand, recently emerging t5 t8 trend to move to an even higher resolution Ultra HD (3840 2160), but so far it is implemented only in a few big TV manufacturers. This ultra-high resolution show Sony KD-65X9005A and Samsung UE55F9000.
In screens and ultra-high resolution still exist TVs with relatively low resolution. Typically, this group includes budget models with small diagonals. For example, Panasonic TX-LR32B6 or Philips 19PFL3507T / 60. Screen Size
Today, the development of LED-TVs has reached such heights that LED lighting is used even in small inexpensive TVs diagonals. So the choice of LED-TVs significantly expanded.
When there is a question of choice diagonal t5 t8 TV, above all, to consider the conditions under which you will watch this TV. Buy a huge TV, maybe it's cool, but put his small room would be quite reckless, no viewing pleasure you get, but in vain will torment firsthand, because any TV when viewing from very close range is noticeable graininess.
Naturally, a comfortable distance promotra will depend not only on the diagonal of the TV, but the resolution. The basic rule is: Full HD TVs recommended viewing distance t5 t8 is about 3-4 diagonal. That is, buying TV 42 inches, which is about 110 cm (like Panasonic TX-LR42ET60 or Sony KDL-42W653), should be alert to the possibility that it will be comfortable to watch from a distance of 3-4
